To aZZ whom itmcg; concern Be it known that l, MARTIN Scrmnnnr, a subject of the Emperor of AustriaHungary, and residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Ball-Bearings, of which the following is a full and complete specification.

The'ohject of this invention is the production of a retainer or cage for rolls, whose purpose is to properly space and position the balls in the inclosing raceway, which is of simple construction, is readily assembled, and Whose parts after assembling are locked in place by the halls themselves.

In general, the retainer consists of an annular structure, or other-shape, whose thickness is less than theballs it contains, and which is made in two sections to permit the insertion of the balls. The dividing" line of the two sections does not follow the line of the greatest dianietcr of the bailshowever, but lies partly on one side and partly on the other side of this middle line. "With such a construction, each section is provided with tongues Which partly surround the halls and in this manner are locked tothe halls and so to each other.

This construction is fully illustrated in the accompanying drawing, in which- Figure l is an end View of the bali been ing, shown partly in section. 2 is aside view of the complete bearing. Fig. 3 is an end vievv' of the retainer and its inclosed halls, showing one form in which the tongues alternate on each section. Fig. d is an end view of another form of retainer,

shown partly in section, in which all the tongues on the exterior are attached to one section and all the tongues on the interior of the retainer are attached to the other ,section.

The two sections of which the retainer is composed are. denoted by the numerals 1 end 2. in the preferred form of construction shown, these sections are made of sheet steel, their interior and exterior faces being a distance apart somewhat less than the diameter of the halls 3, and the connecting edges he- 0 ing shown rounded, the cross section of catch one therefore being practically Ushaped. The balls 3 rotete'in openings formed Partly in the faces of one section and artly in the faces of the other section as sworn in the drawing. Tongues 4- and 5 are thus formed on the meeting edges of the sections and which are integral. therewith. Tongues l, however. are of a length less than the radius of the ball openings and the tongues 5, formed on the complementary section, are of a i'ength greater than the radius of the ball openings. The sides 6 oi the tongues 5 are therefore diverging toward the meeting edges 7" and the edges 7 arelonger than the distance between the openings at their greatest diameter. sections are assembled with the balls 3 in the openings, the tongues 5 can not be'drawn past the halls and therefore the sections are locked to the halls. As both sections carry the tongues 5, both sections are locked to the halls and so to each other.

The raceway in which the halls revolve is formed of two sleeves 8 and 9, shown in the drawing. The distance between these sleeves is somewhat less than the diameter of the halls and somewhat greater than the thickof the retainer described. above. Grooves 1'0 are formed in thesesleeves to give the proper clearencc for the halls and connecting with them are channels leading to one of the sides of the sleeves as shown in Fig. 2. These channels 11 permit the feeding of the rolls into the raceway formed by the grooves 10 in the sleeves 8 and 9.

in assembling this halhoeering, the halls are first fed into the raceway formed in the sleeves 8 and 9 until the right numher have been inserted. A section of the retainer is then forced ov r thehells. As the distance between the sleeves is somewhat greater than the thickness of the retainer, there is space enongh to permit the tongues to spring over the halls 3-and so partly surround them. The-other s'e'ctionis thin forced on and-the bearing is complete.

Froih the construction thus fully described 'a nd shown, it will he seen that it is a hearing of minimum nuniher of parts, is readily made and assembled and can not come apart after assembling. It is obvious, however, that the invention is not limited to the embodiment herein shown and .de scribed. Though it is not deemed advisable, ,it isv possible with the construction shown in Fig. 4 to omit one or the sections and depend upon one section provided with the tongues 5 to space'thehaills. and to he held in place'hy the halls. Further the construction is not limited to hearings but may be used for spacing balls interposed between rectilinear or other curvilinear surfaces.

What I claim is: 1. A ball bearing retaining annulus consisting of companion sections formed with ball retaining tongues ofunequal lengths and adapted to interlock with the balls to be retained to lock the sections to each other.

2. A ball bearing retaining annulus consisting of hollow annular'sections, each section being formed with ball retaining tongues, a part of the tongues of each section being long and a part of said tongues being short, the long tongues of one section being adapted to register with the short 15 tongues of the other section, said tongues having edge portions to engage the balls to be retained and adapted to interlock with said-balls to lock the sections to each other.

In witness whereof I hereunto subscribe 20 my name in the presence of two witnesses.
